The autocorrelator PulseCheck USB is a versatile instrument for measuring the pulse width of different fs and ps laser systems with the ability to cover a broad wavelength range, which can be upgraded in the field.

The PulseCheck USB with PulseLink controller combines the standard PulseCheck optical head with the new PulseLink controller replacing the standard control unit of the PulseCheck. It controls the optical head while being connected via USB to the control software running on the customer’s computer.

Enabled by a special scanner design and a realtime position measurement system the instrument offers a linear time scale and different factory calibrated scan ranges. In combination with a high resolution digitizing and fast processing, the PulseLink provides the measured autocorrelation function and pulse width data at a high refresh rate and with a very high precision.

Furthermore the center wavelangth of the input laser beam is derived from the interferometric autocorrelation data. Using an external trigger the measuring process is optimized for the measurement of low repetition rate laser, too.
